In order to provide for cushioning the downward movement of the pump rodat the end of its stroke and to provide means acting to start the rodhack again, I have provided a spring 26 which, as illustrated, is flatand is disposed in the path of movement of the teeth 1G on pump rod l5and is mounted at the lower. end of the supporting frame l0. Thisspring, as shown in Fig- 'ure 9, is mounted upon a-yoke 27, the ends rodor will have a tendency to start the rod upward. This spring not onlycushions and reacts against the pump rod but assists in securing a quickreturn after ythe down stroke of the pump rod. This quick return issecured through the use of the large segment gear 2O which engages withthe pinion 23 and reverses the movement of the rack. One of theprincipal objects of this mechanism is that it lsaves power as well asincreases vthe amount of water pumped, due to the construction of themechanism and the quick return.

Iv claim 1. A pump rod lift comprising a supporting frame, a constantlyoperated driving shaft,` a counter shaft, a pump rod having rack teeth,intermeshing gear wheels mountedV upon the counter shaft and driveshaft,

`a segmental gear wheel on the counter shaft intermittently engaging therack teeth, a pinion loosely mounted upon the driving shaft, a secondpinion mounted on the driving shaft and meshing with the rack teeth onthe pumprod and rotatable with the first named pinion independently ofthe driving shaft, and a segment gear mounted ,upon the counter shaftand engaging the first named pinion at a time kwhen the teeth of thefirst named segment gear are out of mesh with the teeth of the pump rod.

2. A pump rod lifting mechanism for mills comprising a supporting frame,a driving shaft mounted upon the supporting frame, a driven shaftmounted upon the supporting frame, a pump rod having rack teeth, a piu-.ion'mounted upon the driving shaft, a relatively large gear wheelmounted upon the driven yshaft andrmeshing with said pinion,

a segmental gear mounted upon the driven shaft and intermittently engrIig the rack teeth, a pinion loosely mounted upon the driving shaft, asleeve carried thereby, a second pinion mounted upon the sleeve andengaging the rack teeth of the pump rod, and a relatively largesegmental gear mounted upon the driven shaft-t and engaging said secondnamed pinion at times when the tiistnamed segmental ucar is out ofengagement with the rack har.

3. A pump rod lifting mechanism for mills comprising a supporting frame,a driving shaft mounted upon the supporting frame, driven shaft mountedupon the supporting frame, a pump rod having rack teeth, a pinionmounted upon the driving shaft, a relatively large gear wheel mountedupon the driven shaft and meshing with said pinion, a segmental gearmounted upon the driven shaft and intermittently engaging the rackteeth, a pinion loosely mounted upon the driving shaft, a sleeve carriedthereby, a second pinion mounted upon the sleeve and engaging the raekteeth of the pump rod, and a relatively large segmental gear mountedupon the driven shaft and engaging` said second named pinion at timeswhen the first named segmental gear is out of engagement with the rackhar, the last named segment gear being adjustable upon the shaft onwhich it is mounted.

4. In a pump rod lifting mechanism, a supporting frame, a verticallyrcciproeatahlc pump. rod, the pump rod having rack teeth,

gear wheels having teeth engaging the pump rod, a driving flniftv meansoperated h v the driving shaft for rotating said gear wheels in oppositedirections to cause the reciprocation of the pump rod, and means forenshioning the pump rod at the end ol' its downward stroke and causing areturn impulse to he transmitted to the pump iod comprising a springhaving its free end disposed in the path of movement; ot the lowesttooth oi the pump rod, and a spring supported vohe upon which the springis mounted.

5. In a pump rod lifting mechanism, :i vertically reciprocatahle pumprod, a driving shaft, means operated by the driving shaft and causingthe reciprocation of the pump rod, and means for cushioning the pump rodat the end of its downward slrolie and causing a return impuli-ry to hetransmitted to the pump rod comprising a spring having its tree enddisposed in the path 'of movement of a portion o f the pump rod, and aspring supported yoke upon which the spring isf-mounted.

In testimony whereof I hereunto alli.\4 my signature.
